The appearance of its ads, of course, is a clear sign that the adware knows how to lure people into installing it. This parasite is a deceiver. It hides in bundles, fake updates, corrupted links, spam messages, and pirated software. It lurks in the shadows and waits for you to let your guard down. Do not make that mistake! No anti-virus app can protect you if you throw caution to the wind. Only your actions can prevent infections. The good news is that even a little extra attention can spare you an avalanche of problems. The adware, just like many other parasites, prey on your naivety. Your vigilance, on the other hand, prevents their tricks from succeeding! So, make the right decision. Choose caution over carelessness. Always take the time to do your due diligence. Don’t visit shady websites. Download software and updates from reliable sources only. And forget about the “Next-Next-Finish” setup strategy. If available, use the advanced/custom option.

Dunno Setup jeopardizes your security and privacy. If you take a close look at its ads, you’ll realize that you are in serious trouble. The ads are not random but targeted at you.

Even the Incognito mode can’t hide you. This parasite spies on your every online move. Do you think that ends well? Dunno Setup exists to generate revenue for its criminal owners. These people don’t have your best interest in mind. When their adware collects enough data, they proceed to sell everything.

Take action against the parasite. Remove the adware before it gets a chance to cause you harm.
